CROSS REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation-in-part of U.S. patentapplication Ser. No. 09/933,517, filed on Aug. 20, 2001 by the sameinventor.

BACKGROUND ART

[0002] The invention relates to a swimming pool and, in particular, to apool using deep-sea water. Swimming pools have been so far built on theground or indoors, or, for example, on the deck or indoors in a boat.They have been using fresh water or tap water. That requires theapplication of chemical substances such as chlorine and ozone or othersubstances for killing bacteria for hygienic purposes.

[0003] However, the above chemical substances introduced for hygienicpurposes irritate the eyes and skin of swimmers and, in addition, maycause pain or uncomfortable feeling in the swimmers.

[0004] Also, pools in general have been built on the ground in buildingsand have been surrounded by concrete walls; accordingly, they fail togive swimmers the feeling of openness experienced when swimming at theseashore. Moreover, lagoons or tanks that have been built to supportmariculture are unsuitable for swimming either because they are closed(e.g., tanks) or contain marine plant or animal life that changes thechemical composition of the water, poses a health or safety danger toswimmers, or is otherwise incompatible with swimming.

[0005] Therefore, the invention seeks to provide a swimming pool andsurrounding facilities where people can swim safely and health and anatural environment are promoted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] A description will be given below of embodiments of the presentinvention referring to the accompanying drawings.

[0033]FIG. 1 illustrates a pool in the sea using deep-sea water and thesurrounding facilities according the invention; FIG. 2 is a perspectiveview of one example of a pool in the sea using deep-sea water accordingto the invention; FIG. 3 is a cross-sectional view of another example ofa pool in the sea using deep-sea water according to the invention; FIG.4 is a perspective view of another example of a pool in the sea usingdeep-sea water according to the invention; FIG. 5 illustrates thesurrounding facilities of a shore pool using deep-sea water according tothe invention; and FIG. 6 is a flow chart showing the use of deep-seawater according to the invention.

[0034] In the drawings, 1 represents a pool in the sea which usesdeep-sea water according to the invention; 2 is an intake pipe for thedeep-sea water; 2 a is an intake; 2 b a water inlet; 3 an anchor; and 3a a rope which connects the pool in the sea to the anchor.

[0035] Numerals 5 a, 5 b, 5 c and 5 d are pumps; 6 is a deep-sea waterpumping structure; 7 refers to deep-sea water draining equipment; 7 a adrain outlet; 8 a float for making the pool buoyant on water; 9 apropeller for propulsion used to move the pool in the sea; 10 extensionswhich protrude from the bottom surface of the pool; and 10 a boards of asheet shape which prevent the pool from swaying.

[0036] Numeral 11 is a rope; 12 a deep-sea water storage tank; 13 a poolon land at the beach that uses deep-sea water; 14 desalinationequipment; 15 a post; and 16 a hotel for accommodation built at thebeach.

[0038] The pool 1 which floats on the sea according to the invention canbe freely designed in a size and shape best suited for the location andthe purpose for which it is to be built.

[0039]FIG. 1 illustrates a rectangular parallelepiped shape, but anyshape, for example cylindrical or cubical, can be adopted as long as itfloats on the sea.

[0040] The pool 1 is designed as a floating structure which can beassembled in the sea. The structural materials of the pool walls may bewood, metal (preferably stainless steel), concrete, glass and plastics,closed-cell porous materials such as, for example, styrene foam, arepreferred materials.

[0041] It is desirable that the pool 1 be made of a transparent materialin some parts so that people can see underwater when swimming in thepool or staying at the pool side (deck 1 a). A material such asfiber-reinforced plastic (FRP), which is sturdy and transparent, makingit possible to watch fish in the water, etc., is particularly desirable.

[0042] It is also possible for the pool 1 to use in part sturdymaterial, such as concrete, and use a transparent material only forportions where it is convenient to see while swimming with walls made ofglass or plastic. By combining a sturdy material of metal or concretewith a transparent material of glass or plastic, it is possible toconstruct a more durable pool 1 on the sea.

[0043] Further, the pool 1 can be equipped with a device which providesbuoyancy, such as a float 8 (or a buoy or styrene foam, etc.) in orderto ensure safety. For example, it would be preferred that floats such asrubber inner tubes, used tires, or styrene foam are attached to the pool1 around its perimeter.

[0044] Also, it would be desirable to install a fence consisting of anair permeable shade around the pool side (deck 1 a) in order to increasethe safety on the pool 1.

[0045] As shown in FIG. 1, the pool 1 is supplied deep-sea water throughthe intake pipe 2, the forked intake pipe 21, the deep-sea water pumpingstructure 6, and the water inlet 2 b.

[0046] As used herein, deep-sea water refers to sea water at depthswhere the sunlight does not reach, and which does not vary much inquality, and has a low temperature of about 5 degrees centigrade.

[0047] Also, it is rich in inorganic salts, particularly phosphates,nitrates and silicates, which are required for the growth ofphotosynthetic algae (plant plankton) and are preferably contained instable composition ratios. Further, it preferably contains few parasiticspecies producing parasites on fish and shellfish, few microorganisms,and is comparatively free of heavy metals and artificial pollutants, andaccordingly it features high cleanliness.

[0048] Deep-sea water with these unique characteristics has recentlycome to be considered effective for the therapy of skin diseases, inparticular atopic dermatitis. Indeed, some studies have been undertakento determine what therapeutic effects may result from limited deep-seawater exposure to the skin. As described in the Fragrance Journal (byEguchi et al., 1999, No. 3, pages 45-48), gauze soaked with deep-seawater were placed on specific areas of the skin of patients afflictedwith atopic dermatitis for five minutes and then removed, with the skinwashed thoroughly thereafter. The results of this study suggest thatlimited skin exposure to deep sea water for five minutes can sooth thesymptoms of atopic dermatitis patients.

[0049] The pool on the sea according to the present invention aims toeffectively use such deep-sea water for these unique characteristics.

[0050] The invention is described below referring to the drawings.

[0051] As shown in FIG. 1, the intake pipe 2 for deep-sea wateraccording to the invention has an intake 2 a and a water inlet 2 b. Theintake 2 a is placed to collect deep-sea water from the sea. Preferably,the intake 2 a contains a filtering means, such as sieve 2 a′, thateffectively prevents marine animals (e.g., fish) or plant life (e.g.,seaweed) from being introduced into the pool 1 (or pool 13). Thecollected deep-sea water is supplied to the pool 1 via the water inlet 2b by the pump 5 a of the deep-sea water pumping structure 6. The intakepipe 2, therefore, may be any device which can supply the deep-sea waterto the pool 1.

[0052] For example, the arrangement may be such that the intake 2 a atthe end of the intake pipe 2 is placed at a location for collectingdeep-sea water in the sea, the deep-sea water is drawn therefrom by thepump 5 a provided at the other end of the intake pipe 2, and thedeep-sea water is conveyed via the water inlet 2 b through a water pipefrom the pump 5 a to the pool 1.

[0053] The pool 1 is further equipped with an anchor 3 or the like whichmoors the pool 1 at a fixed location, and, accordingly, it is safelysecured.

[0054] A post 15 for mooring is put up at the seashore to which the pool1 is tied by a strong rope 11 or the like according to the pool size orthe location where the pool is moored, so that safety can be furtherensured.

[0055] Also, the pool 1 has a propulsion device. A propeller 9, forexample, is provided as a propulsion device, and the pool is movable. Itis desirable to equip the pool 1 with a solar array 19 for generatingsolar power (see FIG. 2) or a wind power generator 23 (see FIG. 4) asthe power source for the propulsion device driving the propeller 9;however, any suitable means may be used to drive the propeller 9 and theinvention is not limited to the above.

[0056] In addition, the pool 1 may include a number of extensions 10which protrude from its bottom surface.

[0057] The pool 1 is capable of floating on the sea away from the shore,and, accordingly, there is a possibility that it may be attacked bysharks or other sea creatures that tend to be aggressive. It would bedesirable, therefore, to provide shields on the bottom surface of thepool 1 in order to avoid such attacks from sea creatures so that thesafety of the pool can be maximized.

[0058] For example, stripe-shaped extensions 10 maybe provided on thebottom surface of the pool 1 to protect the pool from attacks by seacreatures. In addition, sheet-shaped boards 10 a may be used to preventthe pool 1 from swaying with the waves as well as to protect from theattack by sea creatures.

[0059] If the extensions 10 are light weight, they would sway with thewaves or the underwater current and frighten sea creatures, and therebyprevent them from approaching.

[0060] As the extensions 10 are provided on the bottom surface of thepool 1 for the purpose of preventing attacks by such sea creatures, theymay have any shape or be provided by any means so long as they canprevent such attacks.

[0061] Moreover, a device for generating frequencies that sea life, suchas sharks, hates, may also be provided.

[0062] Deep-sea water is supplied to the pool 1 from the intake 2 a ofthe intake pipe 2 placed at the bottom of the sea through the pump 5 aby the deep-sea water pumping structure 6.

[0063] However, if the supplied deep-sea water is not maintained freshat all times, it loses its deep-sea water characteristics. For thispurpose, the pool 1 is equipped with deep-sea water draining equipment 7so that, while deep-sea water is flowing in, water is being drained bythe pump 5 b and the deep-sea water is always maintained fresh. Thisarrangement provides the most effective use of the deep-sea waterproperties in the pool 1.

[0064] In addition, the deep-sea water draining equipment 7 allows todrain all of the deep-sea water and makes the work easier when movingthe pool on the sea or cleaning the pool 1. In order to facilitate thedrainage of all the deep-sea water, the pool 1 may have a slanted bottomsurface.

[0065] The pool on the sea 1 using deep-sea water according to theinvention aims to provide facilities where various people can use safelyand enjoy a pleasant time. It also aims to provide a space where peoplespend time in the natural environment without damaging the nature.

[0066] Then, as shown in FIG. 2, it is possible to enjoy watching fish,sun bathing, and napping in the sea air, as well as swimming in the pool1 on the sea. It is also possible to refresh the body if the pool isequipped with a device for generating bubbles using deep-sea water.

[0067] Since it is an object to provide facilities for users to enjoypleasant time in a natural environment, it is desirable, for example, toequip the side of the pool 1 with fishing facilities 17. Especially, ifa drain outlet 7 a for the deep-sea water is placed near the fishingfacilities 17, it will be an ideal fishing site, since fish are fond ofdeep-sea water and gather around it.

[0068] Also, the pool 1 may be designed with a sufficient depth to enjoydiving in addition to swimming. In this case, if a partition 20 (asshown in FIG. 3) is used at a depth suitable for swimming in the pool 1,it will provide safety for the swimmers.

[0069] Diving in the pool 1 would be less dangerous than diving directlyinto the sea and would be appropriate for practicing diving.

[0070] In addition, the pool 1 may be equipped with a device forgenerating fine air bubbles.

[0071] A device for generating fine air bubbles 18 makes it possible toeffectively dissolve air into the deep-sea water in the pool 1, andthereby to purify the water. Further, fine bubbles generated in thedeep-sea water provide an excellent visual effect for swimmers.

[0072] The pool on the sea that is using deep-sea water according to theinvention may be equipped with a means for solar power generation (forexample, a solar array 19; shown in FIG. 2) or a means for wind powergeneration 23 (shown in FIG. 4), which are power generating means fromnatural sources. Such arrangement may be used to energize the propeller9 of the propulsion device, the pump 5 a of the deep-sea water pumpingstructure 6, the pump 5 b of the draining equipment 7, and the like.

[0073] Further, solar power may be used for pumping the water using asolar cell, for example, and the wind power generator can be jointlyused for pumping.

[0074] Also, the pool 1 may be equipped with a desalination device forthe deep-sea water. Equipped with such desalination device (not shown inthe drawing), one can wash with fresh water using a shower 22 on thedeck 1 a after swimming in the pool 1 or during a rest. The fresh watercan be further used for drinking.

[0075] The pool 1 can be, of course, filled with desalinated deep-seawater and be a pool on the sea that uses fresh water derived fromdeep-sea water.

[0076] Swimmers can swim and choose either the deep-sea water or thedesalinated deep-sea water when swimming in the pool or resting on thedeck 1 a.

[0077] In addition, the device for collecting deep-sea water may beequipped with a check valve attached to the pool 1 which only passes anupward flow (not shown in the drawing), so that the deep-sea waterpumped into the pool or the deep-sea water to be supplied to thesurrounding facilities can be prevented from flowing backward anddraining.

[0078] The pool in the sea using deep-sea water according to theinvention may have surrounding facilities that also use deep-sea water,so that the pool can provide deep-sea water properties sufficiently tothe people who come to swim in the pool.

[0079] As shown in FIG. 5, for example, deep-sea water is collected fromthe intake pipe 2 connected to a deep-sea water storage tank 12 on thebeach or seashore. The tank 12, which is connected by pipes to deep-seawater supply equipment, provides to a pool 13 on land at the beachdeep-sea water, as well as to a hotel 16, to dining facilities 24 and tobeauty shop facilities and a fitness gymnasium, and the deep-sea watercan also be used in other facilities built on the beach or seashore.

[0080] The pool 13 on land at the beach using deep-sea water can usewater collected from the intake pipe 2 by the deep-sea water collectingequipment through the storage tank. The pool on land 13 can be used forenjoying swimming in deep-sea water regardless of the weather or thehour of the day at sea.

[0081] For example, if a roof is arranged over the pool 13 on land, itallows swimmers to enjoy swimming even in the rain or at night withoutfear of dangerous sea life.

[0082] In addition, if the deep-sea water collected from the intake pipe2 is desalted to fresh water by desalination equipment 14, it allowsswimmers to swim in the pool on land either using salty deep-sea water(before desalination) or fresh deep-sea water after desalination.

[0083] The pool can be built close to the hotel, and thus, used moreeasily for swimming than the pool on the sea 1.

[0084] A hotel may be built at the beach and equipped with deep-seawater supply equipment connected by a pipe to the deep-sea watercollecting equipment, so that deep-sea water can be used in variousfacilities in the hotel.

[0085] For example, if the deep-sea water can be supplied by pipes tothe bathrooms in the hotel 16 from the deep-sea water supply equipment,it is possible to use either fresh water or deep-sea water for a bath ora shower in the bathroom.

[0086] If the deep-sea water after desalination by the desalinationequipment 14 is supplied to the hotel 16, it further can be used asdrinking water and for cooking, etc., in the hotel 16.

[0087] As mentioned above, the dining facilities 24 and the beautyshop/fitness gymnasium 25 may be built on the beach equipped with thedeep-sea water supply equipment connected to a pipe from the deep-seawater collecting equipment.

[0088] The dining facilities 24, for example, may include a restaurantor a bar, where it is possible to serve food prepared using the deep-seawater and fresh fish provided from the fish breeding facilities 27,which also can use deep-sea water as mentioned below.

[0089] The beauty shop/fitness gymnasium facilities may include a sportsgym which offers deep-sea water showers and JACUZZI brand spas and abeauty salon, which offers face/body packs, massage and shampooing thatuse deep-sea water.

[0090] It is contemplated according to the invention that the deep-seawater used by the pool 13 on land, accommodation facilities (e.g. ahotel 16), etc., in the surrounding facilities can be further used asdescribed below.

[0091] As with the pool in the sea, if the supplied deep-sea water isnot maintained fresh at all times, it loses its deep-sea watercharacteristics. For this purpose, the pool 13 is equipped with deep-seawater draining equipment 13 a so that, while deep-sea water is flowingin, water is being drained and the deep-sea water is always maintainedfresh. The water drained from the pool 13 built on the beach, the hotel16, and the dining facilities 24, as well as the used deep-sea waterfrom the beauty shop/fitness gymnasium 25, can be treated by the wastewater treatment equipment 26 connected by pipes to the deep-sea waterdrains at these facilities. The treated water can then be supplied toother facilities.

[0092] For example, as shown in FIG. 5, the deep-sea water used anddrained by the pool 13, the hotel 16, the dining facilities 24 and thebeauty shop/fitness gymnasium 25 built on the beach, is conveyed to andtreated by the waste water treatment equipment 26 and supplied to thefish breeding facilities 27, fishing pond facilities 28 or hydroponicfacilities 29 built on the beach or at the seaside.

[0093] The fish breeding facilities 27, which use deep-sea water alreadyused by the above facilities, can provide fresh fish that are bred inthe deep-sea water for dishes served at the dining facilities 24 or thehotel 16.

[0094] Also, the fishing pond facilities 28, which may use the alreadyused deep-sea water, can provide the enjoyment of fishing the fish thatare bred in the deep-sea water without wasting the deep-sea water.

[0095] The hydroponic facilities 29, which can use deep-sea water thathas been treated for reuse, are arranged so that vegetables or rice canbe cultivated by desalinated deep-sea water. Since such vegetables andrice are thought to be healthy and highly nutritious, they can be cookedfor dishes served at the hotel 16 or the dining facilities 24.

[0096] Obviously, the fish breeding facilities 27, fishing pondfacilities 28 and the hydroponic facilities 29 can use not only thedeep-sea water after it has been used in the hotel 16 or the pool, butalso fresh deep-sea water.

[0097] It is also desirable that deep-sea water desalinated at thedesalination equipment 14 is used in the facilities described above.

[0098] Accordingly, the use of the deep-sea water, from collectionthrough supplying, is described below and in the flow chart of FIG. 6.

[0099] The deep-sea water goes through the intake pipe 2 and isseparated by a switching valve 4 a to the intake pipe 2 and the forkedintake pipe 21. The deep-sea water which passes through the forkedintake pipe 21 is conveyed to the pool on the sea 1 via the pump 5 a.

[0100] The deep-sea water which passes through the intake pipe 2 isstored in the storage tank 12 via the pump 5 c. The stored deep-seawater passes through the pipe and is separated by a switching valve 4 bto a forked intake pipe 21 a and by the pipes which convey the deep-seawater to particular facilities.

[0101] The deep-sea water which passes through the forked intake pipe 21a is conveyed to the desalination equipment 14, and is desalinated toform fresh water. The salt minerals produced by desalination isprocessed into commercial or consumer salt at a salt manufactureequipment 30.

[0102] Then, the fresh water made from deep-sea water is separated by aswitching valve 4 c to the pipes for the hotel 16 and the pool 13, andto the pipes for the fish breeding facilities 27 and hydroponicfacilities 29, and is conveyed to these facilities through valves thatcontrol access to each of the facilities.

[0103] On the other hand, the deep-sea water that is not conveyed to theforked intake pipe 21 a by the switching valve 4 b, is not desalinatedand is conveyed to the facilities, e.g., the hotel 16, the pool 13,etc., by the switching valves set at each of the facilities. Forexample, at the hotel 16, the water may be used in the bath or showers.

[0104] In this case, it would be preferable to arrange pipes in thehotel 16 so that the deep-sea water desalinated at the desalinationequipment 14 and non-desalinated deep-sea water can be used at theappropriate places within the hotel (e.g. desalinated water would besupplied to drinking faucets while sea water would be supplied toshowers or toilets, for example).

[0105] Then, the deep-sea water used at the hotel 16, the pool 13, thedining facilities 24, and the beauty shop/fitness gymnasium 25, etc., isgathered into the waste water treatment equipment 26 and treated.

[0106] The treated water is further conveyed and used in facilities suchas fish breeding facilities 27, fishing pond facilities 28 andhydroponic facilities 29.

[0107] The water conveyance system may be arranged in a manner such thatthe deep-sea water used at the fish breeding facilities 27 and thefishing pond facilities 28, etc., can be treated again at the wastewater treatment equipment, and again used in the facilities, so that thedeep-sea water can be used as efficiently as possible.

[0108] The collected deep-sea water is thus used in a closed system,i.e. the used waste water is not discharged at sea, making the system ofthe invention environmentally friendly technology that does not generateenvironmental pollution.

[0109] As mentioned above, the pool on the sea that uses deep-sea wateraccording to the invention provides the following various advantages:

[0110] (1) Bathing in the health promoting deep-sea water of the opensea is possible.

[0111] (2) If the pool is equipped with a propeller of a propulsiondevice, the pool on the sea can be moved to a desired location byitself, for example, out to sea during the day and close to shore atnight.

[0112] (3) If the pool has extensions from its bottom surface, theyprevent sharks from approaching, as well as absorb the swaying from thewaves, making the entire pool stable and the deep-sea water thereinstill.

[0113] (4) If the pool is equipped with a deep-sea water drainingequipment and fishing facilities, it is provided an ideal fishing sitebecause varieties of fish like the deep-sea water and gather.

[0114] (5) If the pool is equipped with a means for generating finebubbles in the deep-sea water supplied to the pool, the fine bubbles acton the body's skin and facilitate blood circulation, thus providing abeneficial effect on health and beauty.

[0115] (6) If the pool is equipped with a solar power generation means,the self-generated energy can run the propeller or the pumps for thedeep-sea water during the day.

[0116] (7) If the pool is equipped with a wind power generation means,power can be generated even when the solar power is insufficient to runthe pump or other powered equipment.

[0117] (8) If the pool is equipped with desalination equipment fordesalinating the deep-sea water, the desalinated deep-sea water can besupplied to the pool.

[0118] (9) If the pool has a check valve which only allows an upwardflow, the phenomenon of back-flow that may occur during low tide can beprevented.

[0119] (10) If the pool is at the beach and equipped with deep-sea watercollecting equipment, swimmers can enjoy swimming without worrying aboutthe weather or other hazzards that exist in the open sea.

[0120] (11) In the accommodation facilities built on the beach andequipped with deep-sea water supply equipment, the deep-sea water can beused for drinking water (once desalinated) and in a bath or the shower.
